UNITED STATES JOHN STEWART, OF DULUTH, MINNESOTA.

Application filed. July 16, 1923.

To all 1071 am it may concern:

Be it known that I, JOHN STEWART, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in lVindows, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to windows.

The principal object of the invention is to improve and simplify window construction simultaneously.

Other objects and advantages of the invention will appear in the further descripti on thereof.

Referring now to the accompanying drawing in which like reference characters indicate like parts:

Figure 1 is a broken perspective View of one corner of a window embodying the invention, and

Figure 2 is a transverse sectional view through one side of the window frame.

1 represents one side or the jamb of a window frame, 2 the outside casing, 3 the inside casing, 4 the blind or outside stop, and 5 the inside stop.

6 represents the bottom rail of the lower sash of the window, 7 the glass therefor, and 8 the check or top rail, while 9 represents the lower rail of the uppermost sash, 10 the top rail, and 11 the glass.

In my improved window structure the use of putty is practically dispensed with in that I propose to cover the entire outside of the window sash with sheet metal as indicated at 12, this metal being divided or formed in strips, suitable for the.purpose and joined together at all corners, or in some instances made of an integral piece for an entire sash.

The inside edges of the metal covering are bent inwardly as at 13 to tightly fit against the outer face of the window pane adjacent the edge thereof when the'metal is lying flat against the outer face of the window sash. This metal facing may be fastened to the sash in any desired manner, such, for example as by screws. While reference was made to the absence of putty, it is evident that a small amount may be used, and preferably is, intermediate of the extreme outer corner of the glass and the overlapping lip of the metal facing.

On the lower and side rails of the lower WINDOW.

Serial No. 651,832.

sash the metal facing 12 is turned upwardly and inwardly against itself and then curved downwardly as at 1 1-, the edge terminating in a plane with the first turned edge, forming a groove horizontally of the lower edge of the facing and spaced therefrom twice the thickness of the metal. This groove on the lower edge of the sash registers with the bead 15 formed upon the metal facing16 which is placed upon the upper face of the window sill 17 and may extend any desired distance outwardly thereupon, for example, to the edge of the casing 18 of the frame. The facing 16 I prefer to have extended inwardly under the sill 19, as at 20. p The grooves formed upon the side rails of the lower sash register with and are slidable upon beads 21 similar to the head 15 extending from the metal facing 22 which is securely fastened against the outer face of theframe 1,- thusv forming a weather strip about the sides and lower edge of the lowersash.

Upon the upper rail 8 of the lower sash the metal facing does not extend over the entire outer portion of the rail but is turned downwardly as at 23 forming an upright groove 24, and cooperatively engageable with the upwardly extending edge 25 ofthe metal facing 12 on the lower rail of the upper sash and which facing 12 completely covers the outer and lower faces of the lower rail of the upper sash. The metal facing 12 of the upper sash extends wholly about the same and where it overlaps the upper edge 'of the upper rail as well as the side rails it is turned to form a groove similar to the groove heretofore described and which registers with the bead 26 formed upon the facing 22 which covers the lintel of the window frame as well as, the sides thereof.

It will be understood that by this construction the usual vertical parting strips on the sides of the Window frame are dispensed with and the head 26 forms a suitable guide in lieu thereof, thus materially simplifying the construction of window frames. I

It is obvious that any desired division of the window lights may be accomplished by the insertion of a wooden division strips covered by .the metal facing, and overlapping the edges of the glass, or made of two opposed metal strips.

Having thus described my invention what I claim and desire to secure by Letters Patent, is

1. The combination with a double sash Window having no intermediate strips of a frame therefor Wholly covered with sheet metal facing, said facing having projecting beads thereabouts for en 'a 'ement with corresponding grooves in the sash, the vertically disposed beads for the uppermost sash being adjacent the outer edge thereof, While the vertical beads for thelowermost sash are spaced inwardly from the edges thereof 2. A Window construction of the class described comprising a Wholly metal faced frame, inwardly projecting beads formed upon said facing wholly about the frame, an

upper glazed sash and a lower glazed sash Wholly externally faced With sheet metal,

said facing upon both sashes impinging the glass upon one marginal edge, While the other marginal edges are folded inwardly upon themselves forming grooves for cooperative engagement With the heads in the facing of the frame except the interlocking marginal edges of the upper and lower sashes Where one is formed as a groove and the other as a head.

In testimony whereof I hereunto aflix my signature in the presence of two Witnesses- JOHN STEWVART. Witnesses a S. C. BRoNsoN, S. GEO; STEVENS.
